The utility model relates to a kind of complete power distribution equipment, particularly a kind of prefabricated substation.
All there are a fixed house and special a set of equipment in the most transformer station of China, their volumes are big, floor space big, structure is more coarse, function is complete inadequately, operation is also inconvenient, and their fail safe, reliability and useful life etc. all exist various defectives, do not meet people to the more and more higher situation of town and country power supply quality requirement.When improving this respect situation, Chinese patent once disclosed three utility model patents: (1) " small combined transformer station " (ZL98213365), comprise transformer and low-voltage distribution chamber, transformer and low-voltage distribution chamber integrator, at indoor pasta table, pressure relief valve, Pressure gauge, copper (aluminium) busbar, air circuit and the low pressure leading-out terminal of being equipped with of low-voltage distribution, it is characterized in that: also metering device, indicating device and Electric capacity compensation device will be housed in that low-voltage distribution is indoor, and being provided with the high voltage power distribution chamber, this high voltage power distribution chamber links to each other with transformer.Its floor space is little, and is easy to install and use.(2) " prefabricated substation " (ZL98237577), comprise casing and assemble its interior transformer room, high and low pressure chamber and electric controling assembly, it is characterized in that transformer room and high and low pressure chamber utilize dividing plate integrated, the oil tank wall of the transformer room that is separated into is box body wall, and fin is set outside oil tank wall, high voltage load switch in the electric controling assembly, high-tension fuse, No-load changer shunting switch, the oil immersion of high and low pressure feed line terminals and are adjusted end with its each and are encapsulated in respectively on the control panel of high and low pressure chamber in oil tank of transformer.Its radiating condition is better, replaces air to make dielectric with transformer oil, improves the voltage output quality.(3) " prefabricated substation " (ZL98238482), feature is that transformer is between the high and low pressure chamber, the front and back oil tank wall of transformer room is the dividing plate that itself and the sealing of high and low pressure chamber are separated, the both sides fuel tank of transformer room has fin outward, in the electric controling assembly each adjusted end and is encapsulated in respectively on the control panel of high and low pressure chamber, and the remainder oil immersion is in oil tank of transformer.It is to improve to form on the basis of a last patent.
The purpose of this utility model is to provide a kind of prefabricated substation, and its volume is little, and is multiple functional, safeguards simple and conveniently, satisfies the upgrading urban and rural power grids needs, is more suitable in the open air use.
For achieving the above object, the solution that the utility model is taked is: a kind of prefabricated substation, the oil tank of transformer that comprises casing and assemble in it is the transformer room, hyperbaric chamber, low-pressure chamber and electric controling assembly thereof, the critical piece oil immersion of electric controling assembly is in oil tank of transformer is the transformer room, its each adjustment end is encapsulated in respectively on the inwall of hyperbaric chamber and low-pressure chamber, it is characterized in that thermal insulation layer is arranged on the casing, have down damp-proof layer, oil tank of transformer be the both sides of transformer room respectively have a cover side radiator, after two cover back radiators are arranged.
Because the utility model has been taked the measure of more complete protection against the tide, heat insulation, heat radiation, is more suitable in the open air use than prior art, the while has been improved useful life of transformer station widely, has prolonged maintenance cycle, has reduced maintenance cost.
Below in conjunction with embodiment and accompanying drawing thereof the beneficial effect of the utility model and generation thereof is remake description.
Accompanying drawing 1 is the front view of present embodiment.
Accompanying drawing 2 is that present embodiment is removed protective door under hyperbaric chamber door (3), low-pressure chamber door (2), the low-pressure chamber, and the imagination is removed the front view of instrument installation door (5) on the part low-pressure chamber.
Accompanying drawing 3 is that to cut open oil tank of transformer be end view after transformer room (32) partial sidewall to present embodiment.
Accompanying drawing 4 is vertical views that the present embodiment imagination is removed part transformer chamber cap (29).
In the accompanying drawings, 1-casing, 2-low-pressure chamber door, 3-hyperbaric chamber door, 4-thermal insulation layer, instrument is installed door on 5-low-pressure chamber, 6-ammeter, 7-voltmeter, 8-voltage change-over switch, 9-pressure relief valve, 10-pressure vacuum ga(u)ge, 11-oil level indicator, 12-thermometer, 13-plug-in fuse, 14-shunting switch, 15-high-tension insulator, 16-on-load switch, 17-high-voltage charge display device, 18-hyperbaric chamber, 19-damp-proof layer, 20-fuel outlet valve, 21-ground stud, 22-zero bus, 23-circuit breaker, 24-main bus bar, 25-low tension insulator, 26-current transformer, 27-low-voltage distribution framework, 28-low-pressure chamber, 29-transformer chamber cap, 30-backup fuse, 31-transformer, 32-oil tank of transformer are the transformer room, 33-back radiator, 34-side radiator.
Shown in accompanying drawing 1～4, present embodiment comprises casing (1) and assembles its interior oil tank of transformer is transformer room (32), hyperbaric chamber (18), low-pressure chamber (28) and electric controling assembly thereof, the critical piece oil immersion of electric controling assembly is transformer room (32) in oil tank of transformer, its each adjustment end is encapsulated in respectively on the inwall of hyperbaric chamber (18) and low-pressure chamber (28), thermal insulation layer (4) is arranged on the described casing (1), under damp-proof layer (19) is arranged, described oil tank of transformer be both sides, transformer room (32) respectively have one the cover side radiator (34), after two cover back radiators (33) are arranged.
